Re: how to change a serpentine belt
I am not familiar with the caravan however the tension pulley should be spring loaded try a socket and breaker bar to move the tension pulley it will be quite stiff and there may be a small bolt to hold it in position if you are concerned with the bolts in the area just look at the bracket which the tension pulley is attached and you should be ok.Hope this helps good luck

Belt idler pully or tensioner pully maybe . Pull the serpentine belt off an see if the noise goes away . Just running the engine for a second or two you should be able to tell , an this will not hurt anything .
You'll need a Serpentine Belt Tool and a socket set.
Rotate the Caravan's serpentine belt tensioner assembly clockwise to
relieve the tension on the belt. Slip the belt off the tensioner with
your free hand before rotating the tensioner back to its home position.
Remove the tool.
Extract the two mounting bolts that hold the serpentine belt tensioner
assembly to the Caravan's front engine cover using your socket set.
Depending on your physical size and dexterity, you may find this easier
to accomplish through the top of the engine well or through the
passenger-side wheel well.
Pull the old serpentine belt tensioner assembly out of the Caravan's
engine bay by hand. Place the new serpentine belt tensioner assembly on
the Caravan's front engine cover and bolt it in using your socket set.
Rotate the new serpentine belt tensioner assembly clockwise with the
serpentine belt tool and then place the belt on the pulley by hand.
Rotate the new serpentine belt tensioner assembly back into place.
Remove the tool and close the hood.
You could have a bad or worn serpintine belt. When you replace it make sure all the pulleys are rotating freelyi.e. air compressor, alternator, tensioner idler & power steering pullies to make sure all of their bearings are running freely. Good luck!
Below the altenator is a tensioning pully, insert a 3/8" ratchet or breaker bar in the square hole on the tensioner and release the tension on the surpentine belt and remove the belt. Route the new surpentine belt in place up to the altenator and take the tension off the tensioner and put the belt over the altenator pully. Double check to make sure the belt is riding correctly on all the pullies before starting. Crank the engine over several times before starting to seat the belt.
I have to use a 15mm open/closed end wrench on the tensioner pulley. Use the closed end of the 15mm and pull toward you and use the end of a cresent wrench to use for additional torque. You can slip the belt over the fixed pulley (not the tensioner pulley). Give yourself more room by not using the hood bar and use instead a broomstick on the right side to prop the hood open. I recommend a goodyear gator belt too. Good Luck, you'll need it with a caravan. Its on the left side. its the easyest pully to see.
basically its easy......only a couple steps.....might want a helping hand......first to make it easy they make a tool that gets in hard to reach areas....like where the belt tensioner usually is.....its called crow foot set that ive seen n used....all you do is get the right sized crow foot and put it on the tensioner and release the tension from the belt by pulling toward you (if your on the same side of the truck) then slip the belt off (2nd hands are very helpful here) n slip the new one on......IMPORTANT!!!! MAKE SURE THE RIBS ON THE BELT MATCHES UP PERFECTLY WITH THE PULLIES...CHECK EVERY PULLY TO MAKE SURE THE BELTS NOT HANGIN OFF......let go of the crow foot slowly so u know it seats on the pullies. tell everyone to stand back and startr up
